A few months ago, I had a nightmare that I was part of an intergalactic police force or army. I was in the middle of a ghost town with my imaginary colleagues. And then, a giant monster came out of the ground, and ran at me. While it ran, it screamed out a low yet loud noise, and for some reason, I didn't pull my gun out. As it came closer and closer, I didn't know what to do.
I eventually woke up early in the morning, and found out that my ma's loud snoring was the cause of this nightmare.
